6.72 is the fastest application. It is faster than 6.03 on G200 cards.

about 8500 secs faster than 6.03 on 260-216

While I have only completed 1 WU I hope to see lots more to come.
GPUGrid is good ... seriously you guys are really good at what you!!!
My GTX295 gets about 5600 sec improvement.
I'm running shaders at 1656 and the time step was 17.892 ms

I have a 480 arriving at my house Thursday and I am eagerly waiting for the next new version of ACEMD that it can crunch ... we will see just what these monsters can do.

Thanks - Steve

Another 30% improvement!
Again, well done.

I have received 1 beta WU 6.72.

Takes 8 min 45 sec on GTX 295.

Tomorrow i will report about WU on GTS 250 and GTX 260.

Again, well done.

Improvement at the expense of higher cpu usage?
6.03=1-2%
6.72=3-6%

I'm seeing "reds" in boinctasks for my cpu projects.

Another 30% improvement!

I don't think the improvement is anywhere near 30% it's more like 14% on that type of WU judging by 2 WUs done on ftpd's 295 not a scientific sample but I doubt the improvement is going to be a true 30% on any card just as the last one from 6.71 to 6.03 was anywhere near 60% as i believe was claimed.

On a g200 card the new application is 100% faster than the original ACEMD application which lasted almost one year.
No further improvements are planned.

GTX 260 - WU 6.72 = OK

While the speed increased for some GPUs, it looks like the credit awarded is going down by 2000 points:

Beyond, it looks the top task picked up a 25% bonus rather than a 50% bonus.
Reason, missed 24h deadline by about 3.5h

Turn your cache down to 0.05 or similar.

If you are running CPU tasks and want to keep a few days worth in cache,
stop receiving new GPU tasks, turn up your cache, collect whatever CPU tasks you need (say 5days) then turn your cach right down to 0.05days, and enable new GPU tasks.

We could probably do with a seperate GPU control Tab on Boinc!

I don't think so. Time/step was nearly identical as was the total time for the WU Same computer/GPU.

I agree about the separate GPU cache control, as well as project by project cache control. I've asked DA & company for it. You can guess the response, same as always :-(

Didn't know that the bonus went down after 24hours. With these new long WUs, for now looks like I'll have to be preforming a lot of abortions (of the WU variety)...

Recently the bonus was increased to 50% for tasks completed in 1day. Prior to this there was a bonus of 25% for tasks completed within 2 days – This 2 day bonus still applies.
This is essentially to encourage faster turnaround of tasks, which in turn speeds up the project, as in compound interest (accelerates it)! Presently the CC1.3 cards can all do the longer WUs well within the 24h time frame, but it is important to have a low cache for CC1.1 andCC1.2 cards. It also helps the project to have a lower cache for CC1.3 cards.

The cc1.1 cards can't make the 24 hour limit with the long WUs so they're back on v6.03. The GTX 260 is fine with the .33 day cache. The 3 GT 240 cards have a problem with the 24 hour deadline when using a .33 day cache for the CPU projects. Don't really want to go too much less than that.

I repeat. There is nothing strange about these two workunits, one is simply longer than the other one (time/step is the same but number of timesteps is different).

This long 6.72 task ran on one of my GT240s.
It completed and validated in about 18h; within 1 day, for the full 50% bonus.
6.72 tasks are about 21% faster than the 6.03 tasks on a GT240.
All my systems use a 0.05 day cache.
